Hey...I changed nameservers on my domain name and in the control panel I type:
colinsmiley.com
and it says are you sure, I click yes and it reloads page...its been about 30 min and it still hasn't fixed....is there something wrong with you all's system? Thanks - Colin

What is your hosting account domain? It works here for me.

its http://colin.zymichost.com/

In the box did you enter "colinsmiley.com" without "http or www" ?

Also, your domain hasn't updated the nameservers. You need to make them ns1.zymichost.com and ns2.zymichost.com

http://whois.domaintools.com/colinsmiley.com

Colin just to also let you know, sometimes it takes a couple of hours for the DNS to switch over properly.

I made it redirect to my current site a little while ago...It was set on ns1.zymichost.com and ns2.zymichost.com
And I entered colinsmiley.com first, then I tried www.colinsmiley.com and I have not done it with http...I am pretty sure its without either
Edit:
I am trying to do the same with colinsmiley.net and its doing same thing but its still loading the old host...I checked on that http://whois.domaintools.com/colinsmiley.net and it says:
Domain servers in listed order:
ns2.zymichost.com
ns1.zymichost.com
If this says its updated why is it showing old site???
